“She doesn’t give up. She has a very strong fighting spirit. She’s able to always pull along, to find another way to come back and restart her goals.”

Clinton, 68, once the clear-cut favorite, now seems at times to be sputtering against the upstart Sanders.

In South Carolina, her campaign is hammering the message that she is the only candidate who can break down barriers still preventing minorities from getting ahead.

She notes specifically the cost of college education and the need to reduce the disparity between prison sentences meted out to young black offenders and those given to young whites.

“Right now there are barriers, economic barriers, health barriers, education barriers. We also have to be honest about systemic racism, which is still a problem in America,” Clinton said at a town hall in North Charleston.

– ‘Super Tuesday’ –

Sanders, 74, was in South Carolina Friday for a rally and concert but his prospects in the state are poor and he has invested few resources here.

Instead, he is focusing on states like Ohio and Minnesota that vote in March, when a whopping 45 percent of the delegates who will attend the nominating convention are up for grabs.

That means Reich’s endorsement may have come at just the right time.

“He’s leading a movement to reclaim America for the many, not the few,” Reich said of Sanders.

Since he entered the campaign last year, Sanders has made up some lost ground with minorities in terms of face and name recognition.

Some high-profile African Americans have endorsed him, such as film director Spike Lee and the rapper Killer Mike.

The former first lady’s ties with black Americans, while solid, are not without blemishes.

One supporter of the “Black Lives Matter” movement criticized Clinton at a private event Wednesday for defending in 1996 her husband’s policies that led to a disproportionately high incarceration rate for young African Americans.

Her refusal to publish the text of paid speeches she gave to Wall Street banks and investment firms has also become an issue for some voters.

Another sore point for the Clinton campaign is the FBI investigation into her use of a private email server during her tenure as secretary of state.

But the candidate said she was not worried.

“I am, you know, personally not concerned about it, I think that there will be a resolution on the security inquiry,” she told MSNBC.

Polls carried out through last week gave Clinton a clear advantage in South Carolina: about 56 percent compared to 28 percent for Bernie Sanders.

Things are less clear for Super Tuesday. Clinton is ahead in most of the 11 states that will hold Democratic nominating contests, but Sanders has the edge in Massachusetts and his adopted home state of Vermont.
